The AAS CD-ROM SeriesAstrophysics on DiscVolume VI, June 1996

Up to Table of Contents,
Forward to Introduction
The purpose of this HyperText Markup Language (HTML) documentation is to allow
users of the AAS CD-ROM to browse the disc efficiently using the popular World
Wide Web clients such as Netscape Navigator, NCSA Mosaic or Lynx. In addition
to this document, an Author Index lists all of the contributing authors, Tables
of Contents list the bibliographic references to the papers on the CD-ROM, and
a Directory of Files contains links to every data file and document on the
CD-ROM. By using an HTML browser, one can navigate these links to any point on
the disc quickly and efficiently.

NOTE: If you are using a Unix computer with CD-ROM driver software that
presents file names in UPPERCASE (e.g., Ultrix), a version of this
HTML documentation has been provided with Uniform Resource Locator (URL) file
references in UPPERCASE. If you encounter difficulty following links in this
document, try AASCDU.HTM, instead. If your CD-ROM
driver presents filenames in UPPERCASE with a trailing ";1" (e.g.,
Apple Macintosh), try AASCDM.HTM;1.

Forward to CD-ROM Contents
This is the sixth volume in a series of CD-ROMs containing data published in
papers from the American Astronomical Society's Astronomical Journal,
Astrophysical Journal, Astrophysical Journal Supplement Series,
and Icarus. Also included are data from the Publications of the
Astronomical Society of the Pacific.

This series provides a means for publishing astronomical data in a convenient
and useful format. CD-ROM is an industry standard for reliable high-volume
publishing of software, data, imagery, and text. The AAS has chosen CD-ROM
publishing of data as part of its overall plans for electronic publishing.

This CD-ROM volume contains data, imagery, and graphic line-art from 33 papers.
A complete table of contents is presented below.

The table of contents outlined below contains hypertext links to all papers
that have contributed data appearing on the AAS CD-ROM Series, Volume VI,
June 1996.

The Author Index is a listing of all authors on this volume. The
Table of Contents for the volume contains titles, authors, and
references for each paper, as well as hypertext links to the abstracts and
documentation for each paper. One may proceed directly to a particular journal
by following the appropriate link. The Directory of Files contains
hypertext links to every file on the volume.

The AAS CD-ROM is formatted for the ISO 9660 Standard, Data Interchange Level 1.
Filenames at this interchange level are restricted to at most eight characters,
followed by a full stop, ".", followed by at most a three character extension,
followed by a version number suffix, which will be ";1" in every case. The
appearance of the filenames (upper or lower case, with or without version
numbers) depends on the computing platform, operating system, and device driver
software used to access the CD-ROM. The reader should consult their system
documentation for information particular to their home site's configuration.

Textual data on this CD-ROM are stored as Unix ASCII text files. This implies
7-bit ASCII characters in records delimited by a linefeed character (decimal
value 10, hexadecimal value 0A). Some data were provided by the authors as
Flexible Image Transport System (FITS) tables. In this case, the FITS tables
have been kept on the CD-ROM, and the table data has also been extracted into
plain ASCII text files. Graphic line art is stored in Postscript files
suitable for printing on standard Postscript printers or for viewing by any
application capable of manipulating Postscript data, e.g. Ghostview.

The data are stored in a directory heirarchy based on the CD-ROM volume number,
journal, volume and page of the source paper. By convention, this
documentation uses Unix-style directory paths to denote the location of files
on the CD-ROM, with all paths and filenames in lowercase. The actual directory
path and appearance of the filenames on the reader's computer will depend on
the operating system and device driver being used. For example, data from
CD-ROM Volume VI, with bibliographic reference Smith & Jones, 1996, AJ, 111,
1234 would be found in the directory /cdrom/volume6/aj/v111/p1234 on a
Unix machine that has mounted the CD-ROM on directory /cdrom. On an
MS-DOS machine the path might be E:\VOLUME6\AJ\V111\P1234, assuming the
CD-ROM has been installed as disk E:. An Apple Macintosh computer
would present the data in a hierarchical set of folders named VOLUME6, AJ,
V111, and P1234. Since CD-ROMs can be used by practically every computer and
operating system, it is impractical to document every possible
configuration.

The kind of information stored in each file can be inferred from the extension
appended to each filename, as described in the following list:

DOC

Documentation. Table documents follow the conventions of the the Centre de
Donnees astronomiques de Strasbourg (CDS). See the following section for more
details.

DAT

Table data stored as Unix ASCII text files.

TEX

TeX or LaTeX source, as provided by the author. Tables in TeX or LaTeX
have been formatted into plain ASCII text and stored into a DAT file with the
same name.

LOG

Normally seen as the file change.log, this file contains a record
of the processing history of the data in that directory. There is a different
change.log file for each paper.

FIT

Flexible Image Transport System (FITS) ASCII Table or FITS image data, as
supplied by the author.

PS

Standard Postscript line art. All Postscript files have been previewed by
the Ghostview X Window Postscript viewer to ensure that they are viewable.

Other files, such as LaTeX style files can be found in various directories.

Forward to Credits
Each data set is accompanied by at least three pieces of ancilliary
documentation generated by the American Astronomical Society in preparation of
publishing the data on CD-ROM. These document files are:
abstract.doc, an ASCII representation of the abstract from the printed
paper; change.log, a log of the processing history of the data; and
table.doc, the documentation for the ASCII table(s).

The table.doc file is based on the documentation style of the CDS as
detailed in the document "Astronomical Catalogues at CDS Adopted Standards",
Version 1.4 September 12, 1994. This document is available by anonymous FTP
from host cdsarc.u-strasbg.fr in file
/pub/cats/doc.tex.

The CDS distributes software that will use the standard documentation and table
data to generate FITS ASCII tables. See the CDS document cited above for more
information.

Some data files were submitted as LaTeX source files that use the AASTeX
"planotable" style files. Version 2.2, 3.0 and 4.0 of the AASTeX macro
packages can be found in the directories /dos/aastex22,
/doc/aastex30, and /doc/aastex40, respectively. Most AASTeX
data tables are formatted with the Version 3.0 package, the other packages have
been included for completeness.

Online documentation and browsing capability is provided by this HyperText
Markup Language (HTML) document, aascdrom.htm in the main directory of
the disc. The HTML documentation on the disc provides links to all papers in
all four volumes, including tables of contents, an author index, and an index
to every file on the disc. If your CD-ROM system software returns file names
in uppercase letters (e.g. DEC Ultrix), use the HTML document
AASCDU.HTM. If your CD-ROM system software returns
file names in uppercase letters and includes version numbers (e.g. Apple
Macintosh), use the HTML document AASCDM.HTM;1.
(Please note that AASCDM.HTM;1 is an experimental document included for the
first tine on Volume IV.)

Utilizing the documentation requires a World Wide Web (WWW) client program,
such as Mosaic from the National Center for Supercomputing Applications or
Netscape Navigator from Netscape Communications Corporation. Once the HTML
document is loaded into the WWW program, one can follow the HyperText links to
any abstract, document, or data file on the disc.

It is beyond the scope of this document to fully describe the installation and
use of World Wide Web browsing software. A large amount of information on the
World Wide Web can be obtained by anonymous FTP to info.cern.ch in
directory /pub/www or in many popular books and magazines that discuss
the Internet.
